PLZ Umrechner

PLZ Umrechner is a specialized web utility that converts obsolete four-digit postal codes from former West and East Germany into current five-digit German postal codes. The tool resolves historical address ambiguities resulting from the dual postal systems prior to the 1993 unification reform. It serves genealogists, historians, and archivists by enabling accurate geolocation of addresses in pre-1993 documents and records.
